The Rex® and Link-Belt® Dual Flow screens can be operated continuously or intermittently, depending on requirements. As the water flows through the screen, baskets, typically made of fiberglass with varying size meshes, remove debris. The baskets, mounted to two strands of chain, travel to the top of the screen where high pressure jet sprays of water remove the debris. Depending on capacity, finer mesh screens may be used for increased debris removal.
